Verse twelve adds, Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. Christ did not need the blood of goats and calves to be qualified to enter the most holy place but entered through His own blood sacrificed for us.
Verse thirteen continues, For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: The blood of bulls and goats were used to signify the purifying of the flesh. It was something that had to be done over and over.
Verse fourteen declares, How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God? If the blood of bulls and goats could serve to sanctify us before God, then how much greater is the blood of Christ, the perfect and everlasting Sacrifice. We are purged from dead works to serve the living God. I believe that all works done outside the leadership of the Holy Spirit are dead works, and certainly any works done with the hope of earning salvation are dead. Our worship of God should be based on a relationship with God and not on rituals carried out in the name of God. Only through the blood of Christ, shed for us, can we find salvation.
Verse fifteen adds, And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance. Christ is our Mediator. Once more we are told that through His death we may enter into the new covenant with God. It depends on our acceptance of Christ through faith.
Verse sixteen continues, For where a testament is, there must also of necessity be the death of the testator. In order for a person to receive an inheritance, the one they are inheriting from must die, and Jesus Christ died in order for us to receive the inheritance of everlasting life.
Verse seventeen concludes, For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth. It was only after the death of Christ, and His subsequent resurrection, that we could become heirs of the promise of everlasting life. We simply have to accept by faith in Christ what is already our inheritance when we accept Him.
